Getting discouraged ?

Well, took an ovulation test yesterday and there was a faint line... Then today I took one not even 5 mins ago and there was nothing.. What is going on?? I'm in my fertil window according to glow and my other app. I know it's not my ovulation day but I figured the line would get darker as ovulation day approached. What am I supposed to do? I checked my cervix and it felt like a little round ball that was a little firm but soft. My cm is not dry but dries fast kinda sticky... Can someone please tell me what to feel for when feeling my cervix and the different stages of cm??
